Back from the 90s and early 2000s:
Thai Silk girls:
Legendary Nina - The absolute complete package. She'll never be forgotten.
Momo - Still in contact with her and hands-down still the best slow bbbj ever.
Jenny - Dead ringer for an asian version of Jennifer Love Hewitt.
NYCVIPCAT girls:
Kelly - Moody blonde firecracker. Featured on the cover of DollarBill's book.
Maya - Eventually became MMS at a couple of her own places, but would still ride my face to earth-shattering orgasms. Like an obsessed tiger. Loved her raspy smoker voice.
Yong - Sultry dirty talker.
Lucky's girls: Surprised no one has mentioned one of the best MMSs of all time, maybe just one step below Rhee of Thai Silk
Sky - Petite and erotic to her core. Wasn't in the game very long, but won't be forgotten
Ocean - Best BLS of all time (and I'm not even into that generally). Always wanted to take a nap with me afterwards.
Other notables/more recent:
Yuka at 7 Star - Cute pixie with a tiny tight ass. She might be older, but still holds the allure and charm.
Julie at Jasmine - Teeny tiny. Amazing chemistry for a GND type. Now selling life insurance, but on call when she needs the cash.
Natasha at MAGFE - Not for everyone, but possesses all the tools necessary for a wild time. More than willing to double-team you without notice.
Kiki at KKP - Super friendly and enthusiastic. Would ask me to run errands with her just to have company.
14th St Korean Cougar - One time experience with a tigress who got so into the session that she demanded I ram her ass in every position possible (for no extra charge). Never got a name, never saw her again.
Unfortunately, even though I've had many memorable experiences, this hobby is also fraught with so many more forgettable experiences. I'd say only maybe 1 out of 20 encounters provides that special one. The rest is a sea of mediocrity and meh. Thankfully, this site (and others) makes that ratio better than worse.
